Remote locations in Papua New Guinea will be more resilient and informed about volcano hazards than before with the next stage in an Australian study to be trialled in Rabaul. Geoscience Australia recently published a proof of concept study, which explores the use of satellite monitoring to detect volcano deformation across high-risk volcanoes in Papua New Guinea. The study published in the journal Frontiers in Earth Science combines Interferometric Synthetic Aperture Radar (InSAR) and Global Navigation Satellite Systems (GNSS) data into a method that enables volcano observatories to use the information to make decisions on the eruptive state of volcanoes. The new remote sensing method will now be trialled by staff at the Rabaul Volcano Observatory in Papua New Guinea, following its successful application to historical data for the region by Geoscience Australia. Geoscience Australia’s Chief of Positioning and Community Safety Division, Dr Andy Barnicoat, said this latest publication is the result of many years of work looking at different ways to reduce the risks of volcanoes in regional and remote locations. “Geoscience Australia has been working with Papua New Guinea to develop fundamental information and practices for the effective response and management of natural hazards for over 30 years,” Dr Barnicoat said. “Through this work, it was identified that the Rabaul Volcano Observatory in Papua New Guinea was physically limited in their ability to monitor the 56 volcanoes across the country. “Geoscience Australia has since trialled the use of remote sensing to monitor the activity of high-risk volcanoes using InSAR and GNSS. “This new method gives our Papua New Guinea neighbours the opportunity to exploit openly available satellite data, such as the European Sentinel-1 mission, and pin point where to focus attention across their active volcanoes.” The Department of Foreign Affairs and Trade (DFAT) funds the Disaster Risk Reduction Program at Geoscience Australia through the Australian Aid technical exchange program between Australia and Papua New Guinea. A DFAT spokesperson said the Australian Government has been supporting the work of Papua New Guinea’s national volcanological agency, the Rabaul Volcano Observatory, since the mid-1980s. “Australia’s geoscience collaboration with Papua New Guinea over this time has been very productive, resulting in the development of new maps, modelling and infrastructure to better manage geological hazard risks across Papua New Guinea,” the spokesperson said.
